いる。[Prior Art] Conventionally, when constructing a steel frame structure for a low-rise building, one block was built using two or three layers of steel columns each with a base plate attached, and a girder was attached to the adjacent block. By repeatedly erecting steel columns and installing girders, a steel frame structure with the required floors was achieved. Furthermore, the construction work has been corrected and the girder joints are being finished by bolting or welding. Among these operations, work at high places must be performed from a suspended work floor, and to prevent falls from there, it is necessary to temporarily install safety nets, guide ropes, etc. After the main steel columns and girders are assembled, the small beams are installed and bolts are tightened, and deck plates, etc. are then laid from the lower to the upper floors to complete the steel frame erection. In order to carry out painting work, ceiling work, etc., temporary scaffolding is set up separately from the steel frame work, and work is carried out on it.

目的とする。[Problems to be Solved by the Invention] The above-mentioned conventional construction of steel structures involves dangerous work at high places, so only professionals such as jumpers can perform the work, and temporary materials are required for safety measures. This is necessary for each task, which increases the number of man-hours and takes a considerable amount of time to complete the erection of the steel frame. Furthermore, after the steel frame work is completed, horizontal work such as painting and ceiling foundation work must be done, which lengthens the construction period. Furthermore, when inspecting joints in steel structures, it is necessary to go up to a high position on the steel structure, which causes the problem of time-consuming inspections. Therefore, the present invention eliminates work at heights when constructing steel structures, thereby making it possible for workers other than those working in high places to carry out erection work, enabling safe steel frame assembly, and also allowing for painting work, roofing work, etc. The purpose of this project is to enable horizontal work such as roofing work and ceiling foundation work to be carried out while the steel frame is assembled, thereby saving materials for safe temporary construction and reducing the occurrence of disasters during steel frame construction.

It was designed to be foldable, and the steel structure from the bottom floor to the top floor was assembled into a folded state. Then, the upper part of the top floor is lifted by a crane using a hanging frame jig, and all the collapsed column steel frames are stretched in a straight line, and the joints of each column steel frame are fixed with welding or bolts to complete the construction of the steel structure. Complete the process. Incidentally, along with the assembly of the steel frame for each floor, the deck plates for each floor may be sequentially laid, and horizontal work such as painting work and ceiling work may also be performed.

A single-story column steel frame 1 used for the steel frame construction of a low-rise building is formed so as to be foldable with hinges 2 at two locations, near the column base and near the bottom end of the girder. The hinge 2 is attached to the column steel frame 1 in three ways as shown in FIG. 3 depending on the cross-sectional shape of the column steel frame 1. First, in order to fix the lower ends of the plurality of column steel frames 1 in a predetermined position,
A plurality of base plates 3 are each accurately set at a predetermined installation position.

In this case, using a horse 4 and a jack 5, the folded column steel frame 1 is level-adjusted and installed so that each part is horizontal and vertical. After this, the large beams 6 are set between the installed steel columns 1, and the small beams 7 are also set. Furthermore, the horizontal passage etc. are adjusted and the bolts of the beam are tightened, and the lower end of the column steel frame 1 is welded and fixed to the base plate 3. After this, deck plates 8 etc. are laid on the beams between each column steel frame 1 and tied together, and at the same time painting work is carried out.
Perform horizontal work such as ceiling foundation work and equipment work, and complete work on the lowest floor.

Then, a roofing material 9 such as a folded plate is placed on the assembled steel frame on the top floor. All of the above steel frame assembly and horizontal work from the bottom floor to the top floor will be carried out on the ground. In addition, since all the column steel frames 1 are in a folded state, the height of each floor in the assembled state is 1500 to 2000 mm, and there is no need to work at heights, so safety can be achieved without using much temporary construction materials. be able to work on it.

In this case, the lifting capacity and number of cranes are adjusted depending on the weight of the steel structure. do. That is, the hanging frame jig 11 is attached to the top of the column steel frame 1 on the top floor, and the crane 1 is
By lifting the hanging frame jig 11 using 0, the folded column steel frame 1 on the top floor is made to extend linearly. Note that when extending the column steel frame 1 in a straight line, it is desirable to pull out the inner portion laterally. Further, the lifting jig 11 has a structure in which, for example, a horizontal frame 11a and its upper horizontal bar 11b are connected by a wire 11c so that the steel frame structure can be lifted while maintaining a horizontal state. Then, braces are applied to the bent joints of each straightly stretched column steel frame 1 and fixed with temporary bolts. Next, lift the middle floor and the bottom floor in that order, and attach 1 steel frame to each column.
The erection of the steel structure is completed by fixing the joints using braces and temporary bolts, and welding the joints of each column steel frame 1. If the floor plan of a low-rise building is large, it is also possible to lift the steel frame section by section.

This means that even non-professionals can work safely, less materials are required for safety temporary construction, and the risk of falling during steel frame erection can be reduced. In addition, horizontal work such as painting work and ceiling foundation work can be carried out in parallel with the steel structure assembly work, and safety measures are made easier because the work does not have to be carried out at heights. Furthermore, the inspection of the joints of the steel structure can be carried out before the steel structure is lifted, making the inspection easy.
